My ILETS practice (review it,please)

Dear Sir or Madam,
My name is Katerina Nadtochiy and I am searching for new studying opportunities. I am interested in enrolling in your course and to attain the Tertiary Preparation Certificate. Could you be so kind to give me more details about the Certificate? Specifically, I would like to become familiar with the curriculum and the overall costs of both studying (including supplies) and tests.
My personal background is in the field of Public Relations. I have a Masters degree in mass media communication. I also have more than 9 years of experience however I feel upgrading my knowledge as well as improving my resume with such a respected certificate as the Tertiary Preparation Certificate would definitely help me.
Thank you in advance for the information.
Sincerely,
Katerina
